Answer:

assume it's width as 'x'

So, it's length is '2x-3'

and the perimeter is equal to 66m

Step-by-step explanation:

So,equalize the equation

x + (2x-3) + x + (2x-3) = 66

remove the brackets

2x + 4x - 6 = 66

add 6 to both sides

6x = 60

x = 60 ÷ 6

= 10

so, the length is 2x-3 = 20 - 3 = 17 m

and the breadth is x = 10 m

I'm having a bit of trouble finding out how to find the Domain of this function. Help please!
BabaBlast [244]

In general, the domain is the set of all x-values for the graph.  

The issue here is that this isn't the graph of a function.  A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.

So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.

The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean o
Katarina [22]

Chebyshev’s Theorem establishes that at least 1 - 1/k²  of the population lie among k standard deviations from the mean.

This means that for k = 2,  1 - 1/4 = 0.75. In other words, 75% of the total population would be the percentage of healthy adults with body temperatures that are within 2standard deviations of the mean.

The maximum value of that range would be simply  μ + 2s, where μ is the mean and s the standard deviation. In the same way, the minimum value would be μ - 2s:

maximum = μ + 2s = 98.16˚F + 2*0.56˚F = 99.28˚F

minimum = μ - 2s = 98.16˚F - 2*0.56˚F  = 97.04˚F

In summary, at least 75% of the amount of healthy adults have a body temperature within 2 standard deviations of 98.16˚F, that is to say, a body temperature between 97.04˚F and 99.28˚F.

Approximate the value of 5 π
olya-2409 [2.1K]

Answer with explanation:

→π is an Irrational Number.

→Decimal Representation of π is non terminating non repeating.

\pi=\frac{\text{Circumference of Circle}}{\text{Diameter}}\\\\\pi =3.14\\\\ 5\pi =5 \times 3.14=15.70

⇒5 π =15.70
